To all whom it may concern: K

Be it known that I, WILLIs J. PERKINS, of Grand Rapids, in the county ofKent and State of Michigan, have invented certain new and useful Improvements in Shingle-Machi nes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in shingle-machines, the object of the same being to provide a machine capable of sawing a shingle and planing one surface thereof at a single operation.

A further object of my invention is to provide a shingle sawing machine with an attachment for planing one face of the'shingle and marking a coursing line or lines thereon.

A further objectv of my invention is to provide a shinglesawing machine with an attachment for planing one face of the shingle and beveling the butt and equalizing the length of the shingle at one operation.

A further object of my invention is to provide simple devices for operating and controlling the movements of the tilt-table, also for lining the saw; and with these ends in view nations ofparts, as will be more fully described, and pointed out in the claims.

Inthe accompanying" drawings, Figure 1 is a plan view of my invention with arbor-head removed. Fig. 2 is a View in side elevation. Fig. 3 is a transverse vertical section on the line was, looking toward the front. Fig. 4 is a longitudinal section of the machine. Fig. 5 is a detached view of the mechanism for operating the tilt-table. Fig. 6 is a detached view of the tilt-table and planer. Fig. 7 is a view of one form of planer-knife. Fig. 8 is a detached view o the saw-arbor bearing, and Fig. 9 is a detached view of another form of planerknife.

I A represents the frame of the machine, of any suitable shape and size, provided near its rear'end with the cross-beam a, having a central hearing or step, a, in which the lower end of the saw-arbor Brrests. This saw-arbor is supported near. its upper end below the saw in the two-part bearing B, pivotally secured to the bifurcated bracket B which in turn is pivotally secured to the cross-girt 13 at or near the center thereof. The bracket B is provided at its outer ends with the boxes I), in which the trunnions b of the two-part bearing B are journaled. One of the trunnions 12 projects beyond its bearing and is rounded, while the other trunnion projects beyond its bearing, said projecting portion having a plane face and a screw threaded opening. The other portion of the box or hearing B corresponds in shape and size to the pivoted portion of the box, and is held thereagainstby the bent spring 13*, one end of which is provided with an opening adapted to receive the' rounded trunnion, while the opposite end is provided with an opening for the regulating-screw B which lat- ,ter enters the trunnion and holds the two parts of the box together. By tightening the screw the loose portion of the box is forced evenly against the shaft throughout its entire length by the predetermined tension of the spring, and hence all danger of binding or heating thejournal is obviated.

The lower box, a, is provided with four. 7 screws bearing against the lower end of the arbor, for the purpose of moving. the lower end of the arbor forward or backward, or to the right and left. Thus it will be seen that when the lower end of the saw-arbor is moved the position of the sawand upper adjustable box is correspondingly changed, and hence I am enabled to change the lead of the saw as often as necessity demands.

The frame A is provided on its upper surface with the grooves c, in which'the side edges of the carriage 0 rest and move, and the carriage is provided on one side with the fingers or guards G, which latter overlap the ridge or rail 0 on the top of the frame on the movable dog side, and prevent the carriage from moving sidewise. The edge of the carriage on the stationary dog side, or the side away from the power that propels the carriage, never touches the side of the guide, and hence the power can adjustably connected to theupper end of the [O0 vibrating lever 0*, the lower end of which is pivoted to the frame of the machine. This lever is provided with an oblong slot, 1), in which the crank of the shaft D moves. The dog D is rigidly secured to the carriage, while the other dog, D, is free to slide back and forth to accommodate itself to inequalities in the lengths of. the bolts from which the shingles are cut to hold it while the shingle is being sawed and to release it to set the next shingle.

edge with the projection D having a pin projecting therefrom, which latter enters and rests in the above slot of the bell-crank lever D. This bell-cranklever is pivoted by its short arm to the carriage, and is provided with projecting lugsD, against which rests the free end of the spring D. To the bell-crank lever is rigidly attached the arm D adapted to come in contact with the stop D The spring tends to hold the movable dog in contact with the bolt, and this tendency is overcome when the arm D comes in contact with the stop D". When the carriage is in motion, this arm strikes the stop-at or near the end "of each stroke and releases the bolt and permits the latter to settle down on the tilt-table. As soon as the arm leaves the stop the spring again forces the movable dog in contact with the bolt and holds the latter securely in place.

From the foregoing it will be seen that the spring has but a limited motion, and consequently its tension against the dog is nearly the same whether the dogs be close together or widely separated.

Instead of employing the bell-crank, the spring-actuated or movable dog can be provided with an arm having a roller thereon, which latter at every stroke comes in contact ,withan inclined guide, which draws the movable dog away from the bolt.

The dogs D and D are each provided at opposite ends with the downwardly-pro ectin g stops E, adapted to prevent the spalt from leaving the carriage while the latter is moving in either direction. It frequently happens that the spalt remaining in the carriage after the last shingle has been sawed is too small to be grasped by the dogs, and is consequently free to move from the carriage onto the saw. As the saw revolves at a high rate of speed, the spalt is liable to be thrown out with considerable force, and is consequently dangerous, but when the end stops are employed the spalt cannot leave the carriage and all danger therefrom is obviated.

E is the tilt-table, provided at its inner endin this case with bearings E in which the planer-shaft E is journaled, but by omitting the bearing the device forms a perfect tilt-table for ordinary shingles. This tilt-table is also provided with a laterally-projecting portion, E, which latter terminates outside of the frame A, and is provided with The movable dog D is provided at its outerthe inner ends of the linerscrew F rest, and with the bent spring-key F, adapted to be turned over the cap and hold the latter in position. Each cap F is provided with four liner-screws registering with the recesses in the boxes andadapted to hold the caps away or out of contact with the boxes. The caps are also inclined on their top surfaces, and hence by forcing the springkeys up said inclines, as shown in Fig. 3, the caps are held tightly in place and the shaft prevented from displacement. As the bearings wear the caps can be lowered to compensate for the wear.,

The planer-shaft is preferably made in two parts coupled together, one of said parts, containing the planer-cylinder, being located be tween the sides of the frame tolpermit of its ready removal from the machine, while the other portion passes below one side of the upper portion of the frame, and is provided with a drive-pulley, G, by means of which motion is imparted thereto. The projecting portion E of the tilt-table E is provided with a roller, G, adapted to bear against the guide G and permit the projecting end of the tilt-table that is, the projection from the tilt-table-to move up and down without binding, and also to prevent the driving-bolt from moving it laterally or exerting any strain whatever on the tilt-table supports. The planercylinder G is preferably provided 'with six knives, but may have any suitable number, and is partly inelosed at the rear by the hinged hood G, which can be tilted rearwardly when it is desired to remove the planer-cylinder from the machine, and is bounded in front by the chip-breaker G formed integral with the tilttable. This planer is located under and near one edge of the saw, and hence the two operations of planing and sawing are carried on simultaneously without operators touching the shingle or decreasing the capacity of the machine.

The tilt-table E is provided with the transverse brace H, to which the depending post H is rigidly secured. H is considerably reduced in size, and rests within the oblong box H of the depending standard H which prevents the table from tilting backward and forward, but permits it to tilt laterally. The table is loosely secured at its upper end to the upper end of the depending standard for the purpose of permitting the table to tilt without moving the standard H. This standard is also considerably reduced at its lower end, or provided with a slotted proj ection,H, in which the rearwardlyprojecting finger H rigidly secured to the transverse brace I, rest-s. This finger prevents the standard from vibrating laterally, but permits it to be adjusted back and forth. Thus it will be seen that the depending post moves with the tilt-table when the latter is rocked sidewise, and thepost and standard move therewith when it is tilted at its front and rear ends; and as the boxes or bearings supporting the planercylinder are rigidly secured to or formed inte- The lower end of this post gral with the tilt-table, it follows that the for-- mer follows the movements of the latter, and

is consequently always in position to operate on one face of the shingle.

The upper end of the dependingstandard H is rigidly secured to one end of the bent spring I, the opposite end of which is rigidly secured to the front face of the upper brace, 1 This spring passes over the brace and rests on the upper end of the screw 1 the lower end of which latter passes through a screw-threaded bevel-wheel, 1*, which latter is prevented from moving up with-the screw. As the screw is held against rotary motion, it follows that by turning the bevel-wheel the screw will be elevated. As the screw rises the end of the 7 spring attached to the tilt-table rises, and consequently vertically adjusts the tilt-table.

site direction,the screw descends and thespring carries the tilt-table in the same direction.

The bevel-wheel I", which is located in a boxing on the upper brace, 1 is operated by the bevel-wheel I rigidly secured to the inner end of the shaft J, the outer endof which terminates outside of the machine-frame. The

lower end of the standard H bears against the rear end of the screw J, the front end of which passes through a female screw-threaded bevelwheel, J located within the box J of the lowerbrace, I. This screw is prevented from turning and the bevel-wheelis preventedfrom moving with the screw, and. hence when the bevel-wheel is turned the screw is moved longitudinally. When the screw is moved rear wardly, or toward the saw-arbor, it moves the lower end of the standard in the same direction,and consequently tips the front end of the tilt-table downwardly, and when the screw is moved in the opposite direction the tension of the spring 1 causes the lower end of the standard to follow the movement of the screw. The bevel-wheel J 2 is operated by the bevelwheel J, rigidly securedto the inner end of the shaft J the outer end of which terminates outside of the'niachine.

From the foregoing it will be seen that by simply turning one shaft the tilt-table can be adjusted-toward or away from the carriage, and consequently cut shingles of different degrees of thickness, and by turning another screw it can be adjusted in a horizontal inclination to accommodate itself to the lead of the saw and produce a shingle of uniform thickness in the direction 'of its width.

The tilt-table and the standard and post are supported on the upper and lowerbraces, I I, which latter are connected by the vertical braces K. These braces and the parts at tached thereto are adj ustably attached to the machine-frame to permit them to be moved toward the saw as the latter wears away.

K is a shaft journaled in boxes K rigidly secured to the rear face of the standard H This shaft isprovided at or near its opposite ends with the tappet-wheels K on which the tilting-screws K*,respectively, rest. These screws are made in two or more parts to enable them to be lengthened or shortened, to

enable them to decrease or increase the thickness of the point of the shingle. The tilting-screws are supported in bearings projectbutt of the shingle can be increased or diminished by lowering and elevating these screws. As soon as one of thetilting-screws leaves or moves off the tappets on the tappet-wheel it drops,and the other tilting-screw elevates its side of the tilttable, the opposite side descending by its own weight until said latter side strikes against the butt-screw K, where it remains until again moved upward by the tiltingscrew. Instead of making the screws adjustable lengthwise, the screws'or other devices can be provided with adjustable fingers adapted to move in contact with the tappets and produce precisely the same results, or the tappetwheels K may be arranged to be adjusted vertically independently, and accomplish same results as making screws extensible.

The tappet-wheels are liable to be rotated backward by friction of the pawl in contact therewith. vide the tappet-wheels with notches,into which To overcome this objection, I pro- I the extensible screws drop and prevent this backward rotation.

L is a ratchet-wheel rigidly secured on the shaft K, preferably between the tappet-wheels K Thiswheel is preferably provided with four teeth, for the purpose ofturning the shaft one quarter revolution at each stroke of the pawl L, which. operates the ratchet. The pawl L is pivotally secured at its lower end to the lower end of the lever L journaled on the shaft K, and is held in position in contact with the ratchet-wheel by the'springU, one

end of which is attached to the free-end of the pawl, while the opposite end thereof is connected to the lever L The upper .end of the lever L is connected to one end of the pitman L, the opposite end of which is journaled to the crank L on .the driving-shaft. Thus it will be seen that the pawl is moved in contact with a tooth of the ratchet once at each revolution of the driving-shaft, and hence the shaft K is rotated once to every four revolutions of the driving-shaft. The pawl L is considerably wider than the ratchet-wheel, so as to overlap it on one side, for the purpose of" permitting the'pawl to be held out of engage merit with the ratchetwheel. 1

While sawing shingles knots are frequently encountered; and it is essential to the producthe butts to be taken from one end of the bolt and the points from the other'end. I accomplish this by means of a guard, L, which latter rests under the overlapping or projecting portion of the pawl, aud is adapted to move and hold the pawl out of contact with the ratchet-wheel, and thereby automatically stop the movementsof the tilt-table. This guard is rigidly secured to the lower end of the lever L", which latter is pivoted to the bracket L rigidly secured to the depending post. The upper end of the lever L is connected to a cranked end of the shaft L. By turning the shaft in one direction the guard is moved in or away from the pawl, and permits the latter to uninterruptedly engage the ratchetwheel, and by turning it in the other direction the guard is moved rearwardly and holds the pawl out of contact with the ratchet-wheel, and.

tary movement independently of, the shaft,

and is forced against the recessed hub by the spiral spring M The clutch is provided with a peripheral groove in which the lower bifurcated end of the swinging arm'M rests. This arm is pivotally secured at its upper end to the machine-frame, and is provided with the sliding intermediate cam, M, pivotally connected to the finger M of the rock-shaft M, jonrnaled in the machine-frame. This shaft is encircled for a short distance by the spiral spring N, one end of which is secured to the shaft, while the opposite end is secured to the machine-frame. This spring tends to hold the sliding intermediate cam in an elevated position, out of the reach of the cam on the bevelwheel, and when it is so elevated it does not.

interfere with the movement of the parts. When, however, it is desired to stop the travel of the carriage without stopping the operating mechanism, the shaft M is turned, which mo vebevel-wheel N, secured to the shaft N, carrying the drive-pulley. This pulley is connected to a pulley on the saw-arbor B by the belt N, which runs in contact with the belt-tightener pulley N. 'This pulley is mounted on bearings journaled on parallel bars 0, and is operated by the lever O, which latter is connected by pitman O to the bearing on which the tightener is mounted. The lever O'is pivoted to the upwardly-extending bracket 0, i and is provided with a dog adapted to engage the sector rigidly secured to the bracket. By releasing the lever the wheel can be moved in and out, as necessity demands.

The planer-knives can be of ordinary construction; but I prefer to provide them with a series of grooves near opposite ends. These grooves make ribs on the shingle near the butt and point, which ribs form coursing-lines from which the shingle can be laid, thereby dispensing with the ordinary chalk-line. It is also desirable to bevel the opposite ends of the knives, as shown at Fig. 9, for the double purpose of beveling the butts of the shingles and making all the shingles of uniform length.

This machine is comparatively simple in construction and easy to operate, is durable in use, and turns out a better grade of shingles than the ordinary machine without decreasing its capacity.

It is evident that many slight changes in the construction and arrangement of the different parts of my improvement might be resorted to without departingfrom the spirit of my invention, and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described. I make no claim in this application to pushing or holding blocks located at right angles to the dogs, as the same forms the su bject-matter of my pending application, Serial No. 204,486.
